CARRIAGE-WRENCH.

SPECIFICATION forming part of Letters Patent No. 255,637, dated March28, 1882.

Application filed January 19, 1882. (Model.)

To all whom it may concern:

Be it known that we, PRESCOTT B. Knvs- MAN and JOSIAH MERRILL, both ofGreat Falls, in the county of Stratford and State of New Hampshire, haveinvented a new and useful Improvement in Carriagerenches, of which thefollowing; is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 represents a face view of a carriage-wrench, with oilercombined, in accordance with our invention; Fig. 2, a longitudinalsection of the same on the line a: w in Fig. 1, and Fig. 3 a transversesection thereof on the line 3 y in Fig. 2.

The object of our invention is mainly to improve carriage-wrenches, sothat the movable jaw may be taken out or put in the stock without takingout the screw, and to so arrange the oiler with respect to the stock andthe jaws that the thumb of the same hand which holds the wrench mayoperate the oiler with- The means by which these objects areaccomplished will first be described in connection with the drawings,and then pointed out inthe claims.

The stock A of the wrench, as represented in the drawings, is of aflattened or spread construction in direction of its width, and isformed with a circular opening, 0, near its handle end, and with alongitudinal slot, 0, extending from said circular opening to the fixedjaw B at the head of the wrench. The opposite side walls of thislongitudinal slot 0 have ribsdd, which serve to support and guide themovablejaw B of the wrench, said movablejaw being suitably grooved tofit said ribs, and being adjustable toward or from the fixed jaw B bymeans of a screw, 0. This screw is fitted to pass through the head orfixed jaw end portion of the wrench, and so that a plain portion of itsshank is free to turn therein; but it is restrained from longitudinalmovement by a finger-piece or knob, c, on its outer end, by which thescrew is operated, and by a washer on the inside of the head, secured byapin passed through the screw. The threaded portion of said screw fitswithin a. correspondingly threaded portion of the movable jaw B.

The extended or circular opending b in the stock provides for enteringthe movable jaw B within the slot 0, but is more particularly designedto receive or hold within it an oiler, D, that thus occupies animmediate position between the movablejaw B and the handlefof thewrench. Said oiler may be of ordinary construction, with a spring-bottomfor ejecting the oil by the pressure of the thumb. It may be secured tothe wrench in any suitable away.

The jaws B B are made of considerable length, and so that they willreceive within them the nuts or carriage-axles of different sizes. Saidjaws have V-shaped recesses g g in their faces, and flattened marginalsurfaces h h on opposite sides of their faces, whereby they are adaptedto grasp the nut either with an opposite angular or fiat gripe,whichever is most convenient.

The wrench generally, with the exception of the handle, which may be ofwood, is made of any suitable metal.

A wrench constructed substantially as hereinbefore described, and havingan attached oiler, will be found a usei'ul appendage to any carriage,and, o'ccupyin g but little room in the carriage,will be always at hand.When applied to the nut on the axle of a carriage it holds the nut andkeeps it from dropping or becoming clogged with sand or dirt, and thehand of the manipulator does not come in contact with the nut to becomesoiled or daubed with oil or grease, which it is difficult to remove, asis customary with other wrenches when fitting the nuton by hand; but inusing this improved wrench one hand is left free to handle and turn thewheel, while the operator with the thumb of his other hand, which holdsthe wrench, works the oiler.

lEIaving thus desoribed our invention, we claim as new and desireto'secnre by Letters Patent- 1. The combination, with the stock A,having a. fixed end jaw, B, and opening I), the slot 0, extendingbetween said opening andfixed jaw, and the ribs dd, arranged in saidslot, of
